The 125 GeV Higgs boson properties provide a new, important tool to probe possible new physics at high energy scales, which has not been observed in direct searches at the LHC. I will present ATLAS measurements of the Higgs boson couplings using decays to pairs of photons, W and Z bosons, tau leptons, and bottom quarks with the full 7-8 TeV proton-proton collision data. The results are used to constrain models of well-motivated new phenomena such as Higgs boson compositeness, supersymmetry, and dark matter. I will also discuss the Higgs coupling precision and new physics sensitivity at 14 TeV.
