A torque converter having a converter housing which is coupled to a driving unit, a turbine wheel which is arranged in the converter housing and is rotatable with respect to the converter housing about an axis of rotation and has a turbine wheel shell and a turbine wheel hub which is connected with the turbine wheel shell and which can be coupled with or is coupled with a converter driven shaft. A lockup clutch provides selectable rotational coupling of the converter housing with the turbine wheel, and a torsional vibration damper arrangement is provided in the power transmission path between the converter housing and the turbine wheel hub and/or between the turbine wheel shell and the turbine wheel hub. A friction device is connected parallel to the torsional vibration damper arrangement in the power transmission path for generating a frictional force which may be changed in a selected manner.
