We systematically analyze plasmon-exciton coupling for a quantum dot situated in-between two nanoparticles. To that purpose, we employ a systematic quasi-analytical approach inspired by transformation optics, which allows us to study the impact of geometry and material configurations in the quantum dynamics. We show that the coupling to multipolar dark modes close to the plasmon resonances allows to enter into a regime wheret the dynamics can be reversible and compare our findings to recent experiments. The findings presented here may serve as a guidance to additional future experiments and for the development of new quantum plasmonic devices.
