Abstract

A hydrodynamic coupling device comprises a casing arrangement and a turbine rotor which can be rotated about an axis of rotation (A) in the casing arrangement. The turbine rotor has a turbine rotor shell which supports a plurality of turbine rotor blades, and a turbine rotor hub which is coupled or can be coupled to a drive element for joint rotation. A lock-up clutch arrangement is provided for the optional production of a torque transmission connection between the turbine rotor and the casing arrangement, and a torsional vibration damper arrangement couples the turbine rotor for torque transmission to a coupling element of the lock-up clutch arrangement. A positive drive arrangement is provided on the torsional vibration damper arrangement, which positive drive arrangement is in drive engagement for torque transmission with a mating positive drive arrangement on the turbine rotor. The mating positive drive arrangement is formed integrally on the turbine rotor shell.
