This articles describes quick disconnect drive couplings which compensate for misalignment between shafts. The couplings are used where driven elements are located in sliding mounts so that the elements can be easily withdrawn for service. An example is a photoconductor drum in an electrophotographic machine. Fig. 1 shows a "spherical" ball 10 with hexagonal sides mounted on the driven shaft with a corresponding hex female member 11 on the drive side. Position 1 shows the coupling in the engaged position; position 2 shows the drive end of the coupling in the disengaged position. Positions 3 and 4 illustrate a non-interfering force fit on the drive end despite an angled or misaligned fit. Fig.
