The invention relates to a hydrodynamic torque converter including a turbine wheel arranged inside of a housing, a torque converter lockup clutch, an axially mounted piston, a torsional vibration damper and a hub. The turbine wheel and the piston are rotationally fixed to the input component of the damper. The input component is connected to the hub by means of a connection provided with a circumferential backlash. The output component of the damper is connected to the hub without circumferential backlash.

[ What is claimed is:] [1.]1. A hydrodynamic torque converter having a housing and a converter bypass clutch including a piston, a friction surface and a complimentary friction surface, wherein a substantially circular ring-shaped element is disposed between the piston and the complementary friction in the region of a housing wall and is non-rotatably connected with the piston on the one hand and, on the other hand, can be force locked by the piston in an axial direction and against the friction surface which is provided on the housing, wherein the ring-shaped element abuts the piston along an annular contact surface of the piston such that a force applied to the piston acts upon the ring-shaped element along the annular contact surface.
