Morphology

moment + of + a + couple

The phrase is a straightforward compositional noun phrase: 'moment' (a measure of rotational effect) qualified by 'of a couple' (a pair of equal and opposite forces). Even though the concept is technical, its meaning is directly derivable from the constituent meanings and the standard 'X of Y' compositional pattern, so a learner who knows the parts can infer the MWE's sense.

Etymology

Moment of a couple uses couple to mean a pair of equal pushes in opposite directions and moment to mean the amount of turning they cause. Imagine two people pushing on opposite sides of a wheel; the farther apart they push, the more the wheel will turn, so the 'moment' tells how strong that turn is.
