A hydrodynamic torque converter includes a converter housing and a turbine wheel which is arranged in the converter housing and is rotatable with respect to the converter housing about a rotational axis of the converter The torque converter further includes a lockup clutch for producing a torque transmission connection between the converter housing and the turbine wheel. The lockup clutch has a first friction surface arrangement held by a first friction surface carrier arrangement substantially fixed with respect to rotation relative to the converter housing, a second friction surface arrangement is held by a second friction surface carrier arrangement substantially fixed with respect to rotation relative to the turbine wheel, a contact pressing arrangement for pressing the first and the second friction surface arrangement against one another in fictional contact, and an abutment arrangement at which the first and second friction surface arrangement can be supported substantially in the direction of the aixis of rotation when pressed by the contact pressure arrangement. The first friction surface carrier arrangement has a substantially annular body region connected either directly or indirectly with the converter housing and driver projections which are arranged at a distance from one another in the circumferential direction proceeding from the body region. Respective counter-driver projections at the first friction surface arrangement engage between these driver projections.

A connection arrangement for producing a rotational connection of a hydrodynamic torque converter with a rotating shaft includes at least one connection element arrangable at a housing of the torque converter and having a first connection area connectable to the housing and a second connection area connectable to the rotating shaft, wherein the first connection area has a limited circumferential extension with respect to the rotational axis (A) of the converter. The first connection area may be arranged at the housing via a riveting.
