It's not uncommon to describe the fall of a government as a "parliamentary" coup, if the relevant proceedings of a legislative assembly are characterized by haste and intrigue, rather than debate and deliberation. For example, the French revolution saw 3 such events commonly descried as coups - the the fall of Robespierre on 9-th of Thermidor and the Directory's (technically legal) annulment of elections on the 18-th of Fructidor and 22-nd Floréal. The last one was even somewhat bloodless.
