The discovery of a Higgs boson with a mass of about 125 GeV by the ATLAS and CMS collaborations at the LHC has given access to a new fundamental sector of the Standard Model. The existence of this new particle provides the opportunity to measure its properties, such as the coupling of the Higgs boson to gauge bosons and to fermions. Run 2 of the LHC was completed in 2018 and provided about 140 fb$^{-1}$ of data of 13~TeV $p$-$p$ collisions. Run 3 of the LHC started in 2022 at an increased $p$-$p$ centre of mass energy of $\sqrt{s}=13.6$ TeV. These proceedings discuss the state of the art of the 125 GeV Higgs boson coupling measurements and their implications for the understanding of the Higgs sector.
