A hydrodynamic clutch device, in particular a torque converter or fluid clutch, includes a housing, a turbine wheel in the housing, and a torque-converter lock-up clutch, which is used to selectively produce a torque-transfer connection between the turbine wheel and the housing. The torque-converter lock-up clutch includes at least one substantially annular friction element, which is connected to the turbine wheel in order to rotate with the latter about a rational axis, the element having a friction surface region and a contact element. The contact element is connected to the housing in order to rotate with the latter about the rotational axis and impinges upon the friction surface region of the friction elements to produce the torque-transfer connection between the turbine wheel and the housing. The contact element is connected to the housing assembly in a rotationally rigid manner in a zone lying radially outside the friction surface region.
