I have an important question for shoulder joints. Can an experienced developer answer them please?!

I want to keep the shoulder’s CFrame attached to the character’s torso.

so
RelativeRightShoulder = Character.PrimaryPart.CFrame:ToObjectSpace( RightShoulderJoint.CFrame )

So that I could then do later in the script
RightShouldJoint.CFrame = Character.PrimaryPart.CFrame * RelativeRightShoulder

The problem is I don’t know what should be the RightShoulderJoint

Which of all these should I pick? Is it RightShoulderAttachment?
