You’re using a much more narrow definition of what a coup d’état means.

> The sudden overthrow of a government by a usually small group of persons in or previously in positions of authority.

Or to use Wikipedia’s definition

> A coup d'état (French for "blow of state"), often shortened to coup in English (also known as an overthrow), is a seizure and removal of a government and its powers. Typically, it is an illegal seizure of power by a political faction, rebel group, military, or a dictator. Many scholars consider a coup successful when the usurpers seize and hold power for at least seven days.

Yes, the military can be involved in a coup, but the essential definition does not require their involvement. Different terms might be applied if the military is involved, and based on whether or not the military is the primary driver (as in Myanmar) or is backing one side.
