A coupler for a railway vehicle includes a coupler anchor and a coupler centering device having a pair of arm subassemblies. Each arm subassembly has an upper centering arm connected to a lower centering arm via a torsion bar extending through the coupler anchor. The lower centering arms are connected by a cross link such that movement of one of the upper centering arms causes a corresponding movement of both of the lower centering arms. Each upper centering arm engages a roller that rolls along a curved surface of the centering arm when the coupler is rotated horizontally toward the upper centering arm. A centering stop element prevents the movement of the opposing upper centering arm to generate a restoring force in the torsion bars that facilitates horizontal movement of the coupler. The coupler centering device may be disengaged from an active centering position to facilitate servicing of the coupler.
