Abstract
A driving coupling for the torque transmission in the transmission line of a motor vehicle includes a shaft-hub coupling provided with longitudinal toothings for the releasable coupling of a crankshaft with a coaxially arranged hydrodynamic torque converter. The longitudinal toothings of the shaft-hub coupling have tooth cross-sections which become larger and smaller respectively in the longitudinal direction of the teeth. An elastomer layer is situated at least between the tooth flanks of the shaft and the hub which transmit the torque.
