Some key figures who have worked on the imaginary are Cornelius Castoriadis, Charles Taylor, Jacques Lacan (who especially worked on the symbolic, in contrast with imaginary and the real), and Dilip Gaonkar.
A loose coupling is what makes it possible for these ontologically incompatible entities to exist and act on each other, without shattering (akin to Castoriadis's idea of 'articulation').
The name "Monade" was taken from Cornelius Castoriadis' concept of the "monade psychique" (psychical monad), which was the term Castoriadis used to describe the undifferentiated infantile psyche, before its shattering into the ego, super-ego, and id through the process of socialization.
