Can torque only be caused by a force couple?

[Voliminal]

Is it necessary that torque can only be caused by a force couple? If not, then can you provide examples?

This looks like homework.

You need to show some work on the problem before we can help you.

What do you understand torque is?

A "force couple" implies that there are multiple forces acting upon an object but no net linear force on an object. Is this what you mean by "force couple"?
