A mechanical coupler having a spring element which engages a beveled groove on another element provides backlash-free, but disengageable, mechanical coupling between input and output drives. The device is particularly useful for driving the photoconductor on an electrophotographic copier which requires a constant velocity with zero backlash to match the image of the photoconductor without smear, harmonic striping or velocity mismatch relative to an original image.
