A hydrodynamic clutch device used to establish and to release a working connection between a drive and a takeoff is disclosed. The device includes a housing capable of rotating around an axis of rotation, the housing containing a torus space, which forms a torus volume (TV) with a pump wheel and a turbine wheel, and a clutch space, which forms the boundaries of the clutch volume (CV) and which encloses a mechanical transmission circuit including a bridging clutch designed with a torsional vibration clamper. During the course of the minimum resting phase of the housing, the fluid which is distributed throughout the housing during the operating state decreases from a total volume comprising at least the torus volume (TV) and the clutch volume (CV) to a resting volume (RV), which is located at least essentially underneath the axis of rotation as a result of the force of gravity. A volume reduction arrangement is provided to the housing to reduce the clutch volume (CV) versus the resting volume (RV).
