Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, $H\rightarrow\gamma\gamma$, $H\rightarrow ZZ^{*}\rightarrow 4 \ell$ and $H\rightarrow W W \rightarrow \ell\nu\ell\nu$. 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 7 TeV and 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.
-2 log Likelihood in the $(\mu^f_{{\mathrm{{ggF}}+ttH}}, \mu^f_{{\mathrm{{VBF}}+VH}})$ plane for the $f=H\to \gamma\gamma$ channel and a Higgs boson mass $m_H = 125.5$ GeV.

-2 log Likelihood in the $(\mu^f_{{\mathrm{{ggF}}+ttH}}, \mu^f_{{\mathrm{{VBF}}+VH}})$ plane for the $f=H\to ZZ^*\to 4\ell$ channel and a Higgs boson mass $m_H = 125.5$ GeV. The sharp lower edge is due to the small number of events in this channel and the requirement of a positive pdf.
