Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, $H \to \gamma\gamma, H \to ZZ* \to 4l$ and $H \to WW* \to l\nu l\nu$. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of $\sqrt{s}$=7 and $\sqrt{s}$=8 TeV, corresponding to an integrated luminosity of about 25 fb$^{-1}$. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson.
