Coupling
Definition:
(p. pr. & vb. n.) of Couple
(n.) The act of bringing or coming together; connection; sexual union.
(n.) A device or contrivance which serves to couple or connect adjacent parts or objects; as, a belt coupling, which connects the ends of a belt; a car coupling, which connects the cars in a train; a shaft coupling, which connects the ends of shafts.
