Why does my punch script keep doing weird things like stacking everytime i press e and?

every time i press e the damage seems to stack and it seems that even if i don't press e after pressing e just when my right hand touches a humanoid gets damaged it

Heres the local script

local userinputservice = game:GetService("UserInputService")
local Plr = game.Players.LocalPlayer
local char = Plr.Character or Plr.CharacterAdded:Wait()
local Humanoid = char:WaitForChild('Humanoid')

local Hit = script:WaitForChild("Hit")-- a bool value 

local RemoteEvent = game:GetService("ReplicatedStorage"):WaitForChild('CombatFolder'):WaitForChild('RemoteEvent')
local Punch = game.ReplicatedStorage:WaitForChild('CombatFolder'):WaitForChild('Punch') -- Punch is a animation 

local Debounce = true
local CoolDown = 2
local Key = 'E'

userinputservice.InputBegan:Connect(function(input,IsTyping)
	if IsTyping then return end
	if input.KeyCode == Enum.KeyCode[Key] and Debounce and char then
		Debounce = false
		local Load = Humanoid:LoadAnimation(Punch)
		Load:Play()
		
		
		if Load.IsPlaying and not Hit.Value then
			RemoteEvent:FireServer()
			
			
		end
	wait(CoolDown)
	Debounce = true 
	end
		
	
end)

and heres the server script

local Combat = game:GetService("ReplicatedStorage").CombatFolder:WaitForChild('RemoteEvent')

Combat.OnServerEvent:Connect(function(player)
	local char = player.Character
	if not player.Backpack.KeyBind.Hit.Value then
		player.Backpack.KeyBind.Hit.Value = true
		local Bool = true 
		
		char.RightHand.Touched:Connect(function(h)
			if Bool == true and h.Parent.Name ~= player.Name and h.Parent:FindFirstChild('Humanoid') then
				Bool = false
				local EnemyHumnoid = h.Parent.Humanoid
				EnemyHumnoid:TakeDamage(10)
				wait(1)
				Bool = true
				
			end
		
		end)
wait()
	player.Backpack.KeyBind.Hit.Value = false
	end
end)

In the server script, you're connecting a Touched event to the client's Right Hand every time the Combat remote is fired. To avoid this, simply disconnect the connection:

local Combat = game:GetService("ReplicatedStorage").CombatFolder:WaitForChild('RemoteEvent')

Combat.OnServerEvent:Connect(function(player)
    local char = player.Character
    if not player.Backpack.KeyBind.Hit.Value then
        player.Backpack.KeyBind.Hit.Value = true
       -- local Bool = true - this is unneccessary since the touched connection is being disconnected

	local Collided = false -- this is to check if the right hand collided a part or not. If it didn't the connection would be disconnected after a number of seconds
	local TouchedConnection
       TouchedConnection = char.RightHand.Touched:Connect(function(h)
		TouchedConnection:Disconnect()
		TouchedConnection = nil
		Collided = true 
            if h and h.Parent.Name ~= player.Name and h.Parent:FindFirstChild('Humanoid') then 
                local EnemyHumnoid = h.Parent.Humanoid
                EnemyHumnoid:TakeDamage(10)
            end

        end)

	spawn(function()
		wait(1) -- you can modify this if you want
		if not Collided then 
			TouchedConnection:Disconnect()
			TouchedConnection = nil
		end
	end)
	
wait()
    player.Backpack.KeyBind.Hit.Value = false
    end
end)
