Rotary coupler for a railway car

A railcar coupler system that includes a yoke (220) comprising a front end (226), a rear end (224), a top strap (221), and a bottom strap (223). The top strap and the bottom strap are positioned between the front end and the rear end. The front end comprises an internal bearing surface (264) that is obliquely angled with respect to a central axis of the yoke that extends from the front end to the rear end of the yoke. The system also includes a connector (230) configured to rotate within the yoke such that an axis of rotation of the connector is substantially aligned with the central axis of the yoke when the connector is positioned within the yoke. The connector includes an external bearing surface (262) that is obliquely angied with respect to the axis of rotation of the connector and configured to correspond to the internal bearing surface of the yoke.
