A clutch friction plate assembly (1) comprises a hub (7a, 7b) with a friction plate (2) coaxially mounted on the hub (7a, 7b) such tat rotation of friction plate (2) relative to the hub (7a, 7b) is possible. Acting between the friction plate (2) and hub (7a, 7b) is a relatively high stiffness spring to absorb high torque pulses applied between the friction plate (2) and hub (7a, 7b). Low stiffness springs are arranged to act between the friction plate (2) and the hub (7a, 7b). This in combination with the inertia associated with the input shaft of the gear box provides a mass spring system which can have a sufficiently small resonant frequency so that compression torque pulse associated with the engine at idle can be absorbed, reducing gearbox rattle.
