"Attempt to index nil with 'Name'" how do I fix this?

I'm getting this error when I try and change the part properties through the function - line 20. Any help would be appreciated.

function createCharacterAnchors()
    torso = character:WaitForChild("Torso")
    if torso ~= nil then
        print("found")
        local function createNewAnchor()
            print("started")
            local part = Instance.new("Part")
            part.Transparency = 1
            part.CanCollide = false
            part.FormFactor = Enum.FormFactor.Custom
            part.Size = 0.2 * Vector3.new(1, 1, 1)
            part.TopSurface = Enum.SurfaceType.Smooth
            part.BottomSurface = Enum.SurfaceType.Smooth
            part.Parent = character
                end
            end
        end

        local torsoCore     = createCharacterAnchors()
            torsoCore.Name  = "TorsoCore"
            local torsoCoreMotor        = createNewMotor()
                torsoCoreMotor.Name     = "TorsoCore"
                torsoCoreMotor.C0       = CFrame.new(0, 0.5, 0) * CFrame.Angles(0,      math.pi, 0)
                torsoCoreMotor.Part0    = character.Torso
                torsoCoreMotor.Part1    = torsoCore
