  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.
