A joint for a BHA includes an inner driven rod, an outer drive coupling, and a thrust plate. The inner driven rod includes at least one lobe extending radially therefrom. The outer drive coupling includes a keyway formed therein corresponding to and adapted to receive each lobe. A thrust plate is positioned between at least one side of each lobe and the corresponding keyway. The thrust plate may allow for the reduction of point or line stress loading on the lobe and keyway.
