Abstract
A seal for a servo medium of a torque transmission device (2) in which sealing rings can be dispensed with by providing an annular sealing gap (12) which extends on both axial sides of a servo medium supply and by a special choice of materials and structural configuration in this region, the sealing gap (12) diminishes in size with increasing warming-up of the device (2) which diminution counteracts the decreasing viscosity of the servo medium.
