Abstract
Various embodiments may include a clutch assembly comprising: a first coupling and a second coupling; and a vibration damper with a spring. The first coupling includes a crankshaft connection and a coupling-in element which can be connected to one another in a controlled manner. The second coupling has an output connection and an intermediate element which can be connected to one another in a controlled manner. The spring connects the intermediate element and the coupling-in element to one another.
