The invention is based on a rotor device with at least one rotor that is supported rotatably about a rotor axis, and with a drive unit which is provided for driving the at least one rotor and which comprises at least one drive shaft with at least one section that extends, in at least one operating position of the at least one rotor, at least substantially parallel with respect to the rotor axis. It is proposed that the rotor device comprises a compensation unit which is provided to permit a change of an orientation of the rotor axis with respect to the at least one section.
