  In view of the absence of any direct sign of New Physics (NP) at the LHC, the
precise investigation of the Higgs properties becomes more and more important
in our quest for physics beyond the Standard Model (SM). Coupling measurements
play here an important role and not only complement the reach of the LHC but,
depending on the physics scenarios, also allow for tests of NP scales beyond
the ones accessible at present colliders. In this context, various
representative scenarios beyond the SM will be reviewed.
