Abstract
A shaft system for transmitting a torque includes a first component configured to deliver torque from a drive shaft, a first shaft connectable to the first component, and a second shaft connectable to, and axial extendable relative to, the first shaft. The first shaft includes a toothed structure configured to mate with a toothed structure of the first component in a first coupling, and to mate with a toothed structure of the second shaft in a second coupling, such that in operation of the shaft system, torque is transferred from the first component to the second shaft via the first shaft.
