A marking device for golf balls comprises a seat, an arch-shaped retainer, and a bottom plate. The joint module includes a housing component attached to a proximal prosthetic device, an elastomeric polymer attached to the housing component and a yoke component attached to the elastomeric polymer and to a distal prosthetic device. Additional layers may be bonded to the base layer andor the structured layer to form bonded aerogel composites. In addition, methods for treating ocular infections, for example, corneal infections, are included. The invention also extends to the use of the genetically modified non-human animals of the invention for pharmacological andor toxicological studies. It is provided that open-loop torque control for the power train takes place via the adjustment, in dependence on specifiable operating states of the power train, of a mechanical tension acting on a wraparound means of the belt-type transmission.
