Applications of this type require a flexible coupling of small overall depth, high running accuracy even where the fan roller is mounted on one side, sufficient elasticity in order to compensate for misalignment, adjustment to the particular environmental conditions, for example high conveyed-medium temperatures or aggressive media. In the event of the drive motor being dismantled, rebalancing should not be necessary. The couplings known in practice for such applications meet these objects only to a very limited extent since, being made of elastic or thermoplastic material, they cannot be used at high temperatures or for larger drive outputs. Couplings wound from spring steel wire are too expensive and not suitable owing to their large overall depth. The object is met according to the invention in that the two halves of the coupling of non-ferrous metal or highly stable, heat-resistant thermoplastic are so designed (Fig. 1-6) that a standard commercial O-ring or alternatively one of Viton or comparable material assumes a shape approximating to a polygon, resulting in a high transmission torque with sufficient elasticity and good alignment. Rebalancing is not necessary in the event of dismantling. <IMAGE>
