1. An apparatus comprising:
a downhole tool operable to connect within a tool string, wherein the downhole tool is operable to connect together a first portion of the tool string and a second portion of the tool string and facilitate relative angular movement between the first portion of the tool string and the second portion of the tool string when the downhole tool is connected within the tool string, and wherein the downhole tool comprises:

a second body;
a ball member connected to the first body and disposed within the second body, wherein the ball member comprises a first face, and wherein the first face comprises a first flat surface;
a ring disposed within the second body, wherein the ring comprises a second face, and wherein the second face comprises a second flat surface; and
a biasing member disposed within the second body, wherein the biasing member is operable to apply a force to the ring to force the second face against the first face to urge relative angular movement of the ball member and the ring to thereby urge relative angular movement of the first body and the second body toward a relative angular position in which a central axis of the first body and a central axis of the second body are axially aligned.
