    • n coupler One who or that which couples, joins, or unites. Specifically— In organbuilding, a mechanical contrivance by which the keys of one keyboard are so connected with corresponding keys of another that when the former are depressed the latter are also depressed, and thus both can be played by a single motion. Manual couplers connect manual keyboards with each other; pedal couplers connect the pedal keyboard to a manual. Unison couplers connect keys of the same pitch; octave couplers (sometimes loosely called super-octave or sub-octave) connect keys an octave apart. Octave couplers are sometimes arranged between the keys of a single keyboard, so that it may be coupled with itself. Couplers operate in only one direction; that is, the second keyboard may be coupled with the first, but not the reverse. Also copula.
    • n coupler In zoology, a plate which joins one of the swimming-appendages of a crustacean to its fellow on the opposite side of the body.
