A bolt coupling device which has a body with a chamber, an inlet and an outlet. The coupling device includes a coupling mechanism. The coupling mechanism includes a threaded surface along a bolt receiving channel. The coupling device includes a spring member that urges the threaded surfaces toward a first axis, and a cam member between two coupling segments which is rotatable. The cam member separates the first and second coupling segments to increase the dimension of the bolt receiving channel to selectively engage and disengage a bolt. The cam member can be positioned along a second axis which is parallel to the first axis or perpendicular to the first axis.
