A coupling arrangement between two structures, namely a housing 8 containing a motor, gearing 5 and a drive shaft 3, and a drive housing 1 containing a pulley wheel 2 supported on the shaft 3, comprises mutually engaging toothed members concentrically surrounding the drive shaft 3. One of the members comprises an outer ring 10 of deformable material provided with internal teeth 9 meshing with external teeth 8 formed on an annular projection 7 of housing 6. The outer ring 10, which is connected to the drive housing 1, is surrounded by a tension band 15. <IMAGE>
