  In this article, we develop a description of topological pumps as slow
classical dynamical variables coupled by a quantum system. We discuss the cases
of quantum Hall pumps, Thouless pumps, and the more recent Floquet pumps based
frequency converters. This last case corresponds to a quantum topological
coupling between classical modes described by action-angle variables on which
we focus. We propose a realization of such a topological coupler based on a
superconducting qutrit suitably driven by three modulated drives. A detailed
experimental protocol allowing to measure the quantized topological power
transfer between the different modes of a superconducting circuit is discussed.
