A torque transfer mechanism includes an input member to receive an input torque from a propulsion source, and an output member coupled to the input member to transfer the input torque to a driveline component. The torque transfer mechanism also includes a damping mechanism disposed between the input member and the output member. The damping mechanism includes at least one clockspring that is coiled about a center axis of rotation of the input and output members and couples the input member to the output member. The at least one clockspring, which may include a first clockspring fixed to a second clockspring, is arranged to damp vibration associated with the input torque and is coiled in multiple planes such that the clockspring does not contact itself under torsional deflection. The first clockspring may be wound in a clockwise direction, and the second clockspring may be wound in a counterclockwise direction.
