Hostler with humanoids causes characters to lean

Help and Feedback Scripting Support
#1

The way I do hostler is take a fake torso identical to a character torso, put a model where it should welded, once the player has acquired an appropriate tool with a hoslter it takes the model parts and welds them to the fake torso whereas the rest of the model parts are welded to the origin part, causing the cframes to be the same when placed on origin part (fake torso).
But this has caused an issue where attempting to weld a model with multiple parts/humanoids, it causes the character to lean.

	for _,v in _itemHolster._Parts:GetChildren() do
		return v.Name == _part.Name and v or nil
	end
end

local function _RigParts(Part)
	local _rigFolder = _findFolder(Part)
	if _rigFolder then
		for _,v in _rigFolder:GetDescendants() do
			if v:IsA("BasePart") then
				--v:SetAttribute("OriginalTransparency", v.Transparency)
				if v.Name == "FakeTorso" then
					v:Destroy()
					continue
				end
				local Weld = Instance.new("Weld")
				Weld.Name = v.Name.."W"..math.random()
				Weld.Part0 = Part
				Weld.Part1 = v
				Weld.C0 = _rigFolder.FakeTorso.CFrame:Inverse()
				Weld.C1 = v.CFrame:Inverse()
				Weld.Parent = v

				v.Anchored = false
				v.Massless = true
				v.CanCollide = false
				v.CanTouch = false
			end
