Hey there!
The moment of couple refers to a pair of forces that having equal magnitude acting in inverse directions and is set apart at a certain distance.
When the forces are equal and inverse to each other, they cancel out each other and the resultant force is always zero (0) for a couple.
It creates rotational motion only and there is no translation motion.
Hope this helps :)
