1. A torque transmission arrangement comprising: a cylindrical friction element carrier and a snap-ring, wherein the friction element carrier is configured for carrying at least a pressing plate and a reaction plate of an outer friction-based torque-transmission mechanism rotationally secured to an outer surface of the friction element carrier and at least a pressing plate and a reaction plate of an inner friction-based torque-transmission mechanism rotationally secured to an inner surface of the friction element carrier, wherein the cylindrical friction element carrier comprises a plurality of through-holes distributed around the circumference of the friction element carrier, and wherein the snap-ring comprises a plurality of radial projections distributed around the inner or outer circumference of the snap-ring and configured to extend through said through-holes when the snap-ring is mounted on the friction element carrier, such that the snap-ring when mounted on the friction element carrier protrudes in a radial direction beyond both the inner and outer surfaces of the friction element carrier for retaining the inner and outer reaction plates of the inner and outer friction-based torque-transmission mechanisms on the friction element carrier, wherein the torque transmission arrangement further comprises an outer hub member, an inner hub member, an outer actuating device, and an inner actuating device, wherein the outer friction-based torque-transmission mechanism includes at least one friction disc rotationally secured to the outer hub member and located axially between the pressing plate and reaction plate of the outer friction-based torque-transmission mechanism, wherein the inner friction-based torque-transmission mechanism includes at least one friction disc rotationally secured to the inner hub member and located axially between the pressing plate and reaction plate of the inner friction-based torque-transmission mechanism, wherein each of the inner and outer actuating devices are configured for selectively exerting an axial pressure on the inner and outer pressing plates, respectively, for selectively axially compressing the at least one friction disc against the inner and outer reaction plates for establishing a torque transmission path through the outer and inner friction-based torque-transmission mechanisms.
