Title: Torque transmission device

Abstract: A torque transmission device includes a first shaft is coaxially borne relative to a second shaft via at least one roller bearing. An adjusting device adjusts the amount of torque transmitted from the first shaft to the second shaft by changing the internal bearing friction experienced by the at least one roller bearing. In one embodiment, the adjusting device causes one ring of the at least one roller bearing to axially displace relative to a second ring of the at least one roller bearing, thereby changing the amount of bearing friction experienced by roller bodies disposed between the first and second rings and thus the amount of torque transmitted from the first shaft to the second shaft.
