ABSTRACT:
A removable coupling device comprising a boss member with a central axial hole and radial holes opening into the axial holes containing locking balls which engage with a circumferential set groove of a shaft inserted into the axial hole. The boss member has inclined surfaces sloping radially inwardly and away from the apertures. An axially movable set ring selectively forces the balls, into the holes and has a spring ring engaged with a groove of the set ring and radially inwardly presses the inclined surface so that the set ring automatically returns to the position in which the balls lock the shaft.
