A torsional vibration damper assembly for a hydrodynamic coupling device, in particular a torque converter, comprises a primary side having a plurality of cover disk elements, a secondary side which is rotatable with respect to the primary side about an axis of rotation against the action of a plurality of damper springs, a central disk element engaging between the cover disk elements, and a turbine wheel having a turbine wheel shell. The plurality of cover disk elements are fixedly connected to one another on the radial outer side of the damper springs, and a cover disk element located directly adjacent to the turbine wheel shell is fixedly connected to the turbine wheel shell on the radial inner side of the damper springs by connection elements of a first set of connection elements. The connection elements of the first set of connection elements do not produce a fixed connection between the cover disk elements on the radial inner side of the damper springs.

A clutch arrangement includes a clutch device for transmitting torque between a clutch housing and a takeoff, wherein a pressure element and an opposing pressure element cooperate to establish and release a working connection between at least one drive-side clutch element and at least one takeoff side clutch element. The opposing pressure element is mounted nonrotatably and without freedom of axial movement on the clutch housing, and is connected to at least one drive-side clutch element by axially acting energy storage devices. A takeoff-side clutch element is located between a drive-side clutch element and the opposing pressure element, and between any adjacent drive-side clutch elements. Alternatively, the axially acting energy storage devices can connect the drive-side clutch elements to the clutch housing.
