The device (10) comprises a housing (12), a pressure plate (20) attached to and moving in coordination with the housing (10), a spring arrangement (26), and a friction disc (36), provided with an abrasive coating (66) at the side pointing away from the pressure plate (20). The friction plate (36) is joined to the pressure plate (20) in order to confine a motion away from the pressure plate (20) and to a avoid a deformation otherwise caused by the centrifugal forces.
