  In this work we consider a scenario where the dark energy is a dynamical
fluid whose energy density can be transferred to the dark matter via a coupling
function proportional to the energy density of the dark energy. In particular,
we investigate this model's ability to address the $S_8$ tension and find that
against data from Planck, BAO and Pantheon the model 1) can significantly
reduce the significance of the tension, 2) does so without exacerbating nor
introducing any other tension (such as the $H_0$ tension) and 3) without
worsening the fit to the considered data sets with respect to the $\Lambda$CDM
model. We also test the model against data from weak lensing surveys such as
KiDS and DES, and find that the model's ability to address the $S_8$ tension
further improves, without a significant impact on any other parameter nor
statistical measure.
