This glosses over one very important point: the Constitution was ratified by every State.

It was a change in government to be sure, but a coup is the wrong word. Or at least an extreme exaggeration.

A coup replaces the rulers suddenly; no such event happened.

First, the overwhelming majority (42/55) of the Convention delegates were part of the existing government. Any resistance was on the actual terms of the Constitution not who was taking over. In fact, the first President was elected unanimously.

Second, the Convention plus ratification by three-fourths took over a year.
