Abstract
A coupling may be used to couple a top drive to a traveling block in a drilling rig. The coupling comprises a beam that is movable between a retracted configuration in which a becket or bail may be passed behind the beam to a closed configuration in which the beam is linked behind the becket or bail. The beam may include a compound curvature contact area that mates with a corresponding contact area of the becket or bail. The coupling may be remotely actuated.
