Abstract
Combining individual measurements of Higgs boson properties provides enhanced sensitivity and enables precise tests of the Standard Model. These proceedings present a recent combination of ATLAS analyses based on the full LHC Run~2 dataset comprising $140~\text{fb}^{-1}$ at $13~\text{TeV}$, yielding the most precise ATLAS results so far of Higgs boson couplings and production and decay cross-sections. In addition, four dedicated analyses of Higgs boson decays to (vector) bosons are discussed. Two of these focus on $H \to WW^{*}$ using the full Run~2 dataset, while the other two present the first Run~3 measurements of $H \to ZZ^{*}$ with $56~\text{fb}^{-1}$ of early data collected at
$\sqrt{s} = 13.6~\text{TeV}$. All results presented agree with predictions, attesting to the remarkable precision with which the Higgs boson continues to conform to the Standard Model expectations.
