Abstract
A mechanical coupling arrangement includes first and second pins and a sphere. When coupled, the pins are longitudinally aligned and include partial portions that face one another. The second pin's partial portion includes a recess formed therein that faces the first pin's partial portion. The recess is spherically-shaped to be smaller than a hemisphere. A sphere is ring-staked into the first pin's partial portion and is seated in the recess.
