  Overview on top couplings measurements is presented, and the prospects of
future measurements are discussed. The coupling of top to the W boson can be
examined either by looking at the decay of the top quark or from single top
quark production. With the advent of high statistics top physics at the LHC and
at the high-luminosity LHC, the processes where the bosons (photon, Z and
Higgs) are produced in association with top quarks become accessible. The first
evidence on the coupling of the top quark to these particles will come from the
production rate.
