ABSTRACT:
A rotary coupling device comprises driving and driven elements which are rotatable about a given axis. A coupling member of elastomeric material rotatable about the aforesaid axis is interposed between such elements for imparting rotary motion therebetween. The coupling member is connected at spaced circumferential points to the driving and driven elements, respectively, and is so constructed as to have two different torque characteristics, the first being resilient in a range of torques varying from zero up to a predetermined value and the second being relatively non-yielding for torque values higher than such predetermined maximum. The imposition of torques above said predetermined value results in substantially direct drive between such elements and those below said value results in a resiliently flexible drive therebetween.
