How to apply a BodyAngularVelocity to a Humanoid?

How would I go about making a Character spin using BodyAngularVelocity. I've tried inserting it into the Humanoid, HumanoidRootPart, Torso, with AngularVelocity (0,5,0) and nothing happens.

This script is when you press D, the HumanoidRootPart spins on the Y axis. But it doesn't spin when I press D. (This is a LocalScript in the Character's Model)

local Player = game.Players.LocalPlayer 
local mouse = Player:GetMouse()

    --- d
    mouse.KeyDown:Connect(function(Key) 
     if Key == "d"  then
            script.Parent.HumanoidRootPart.BodyAngularVelocity.AngularVelocity = Vector3.new(0,2,0)

    end
end)

mouse.KeyUp:Connect(function(Key) 
 if Key == "d" then
    script.Parent.HumanoidRootPart.BodyAngularVelocity.AngularVelocity = Vector3.new(0,0,0)

    end
end)
