- the roll mounting can be done, for example, by mounting the roll neck in the roll bearing.
- the drive torque of the motor is transmitted to the roll and the reaction torque is transmitted to the roll bearing housing.
- the arrangement of the clutch within a connecting element that connects the bearing housing to the transmission or the motor is particularly advantageous, with the clutch being designed in multiple parts.
- a particularly favorable embodiment is characterized in that an alignment of the transmission that deviates from the axis of the rotatable roller can be compensated for by the clutch.

Compensation for a different alignment of the roller and gear takes place between the first clutch element and the third clutch element and/or through the compensation between the second clutch element and the third clutch element. This can easily be realized by a toothing between the first clutch element and the third clutch element, or the second clutch element and the third clutch element.
- the first clutch element or the second clutch element comprises a clutch hub, for example.
- the coupling comprises a shrink disc, the drive torque of the motor being able to be transmitted to the roller via the shrink disc, and the shrink disc being connected to the roller.
