A composite driveshaft includes a body having a first end, a second end, and an intermediate portion defining a driveshaft axis (DSA). The first end defines a first coupling region and the second end defines a second coupling region. At least one of the first and second coupling regions defines a virtual hinge configured to accommodate both bending moments and axial changes of the body.

A compensating coupling connects a first shaft to a second shaft along an axis of rotation. The compensating coupling has a first coupling body connected to an end of the first shaft and a second coupling body connected to an end of the second shaft. At least one elastic coupling element has a longitudinal axis lying in a plane that is oriented perpendicularly to the axis of rotation. The two coupling bodies are arranged with respect to one another to form a three-dimensional coupling region in which the elastic coupling element is arranged. The elastic coupling element is connected to the two coupling bodies such that the two coupling bodies are displaceable in the radial direction with respect to the axis of rotation. The elastic coupling element is displaceable in the axial direction with respect to the axis of rotation.
