Abstract
A self-aligning coupling linkage for a drive train, of a hair cutting appliance having a driving shaft and a non-aligning output shaft, includes a joint section having first and second connector portions that are configured to engage one another for torque transmission. The first second connector portions define a male connector having an external polygonal profile, viewed in a cross-sectional plane perpendicular to a longitudinal axis, and a female connector having an internal engagement profile. The male and female connectors are arranged in a self-aligning fashion for angular offset compensation, where wherein at least one of the male and female connectors is provided with at least one circumferentially arranged deflectable compensation element configured to urge the male and female connectors towards a centered alignment.
