How can I make the section-text in a Table of Contents clickable, but keep the section-number *unclickable*?

Question

I recently found this thread on how to make section titles clickable/return to their entry in the Table of Contents -- only problem is, the title text of the section headers are clickable, but the numbers are not. I simply want to make the Table of Contents mirror this style.

Here is a template document:

\documentclass[11pt]{article}
\usepackage[margin=0.5in,footskip=0.4in]{geometry}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\hypersetup{
    colorlinks=true,
    linkcolor=blue,
    linktoc=all,
}

% For clickable section headers
% See https://tex.stackexchange.com/a/251964/73149
\makeatletter
\let\hypersection\section
\def\section{\@ifstar\starsection\mysection}
\def\starsection{\hypersection*}
\newcommand{\mysection}[2][\@empty]% #1=optional (toc), #2=title
{\ifx#1\@empty \hypersection[#2]{\hyperlink{toc.section.\thesection}{#2}}
 \else \hypersection[#1]{\hyperlink{toc.section.\thesection}{#2}}
 \fi}
\let\hypersubsection\subsection
\def\subsection{\@ifstar\starsubsection\mysubsection}
\def\starsubsection{\hypersubsection*}
\newcommand{\mysubsection}[2][\@empty]% #1=optional (toc), #2=title
{\ifx#1\@empty \hypersubsection[#2]{\hyperlink{toc.subsection.\thesubsection}{#2}}
 \else \hypersubsection[#1]{\hyperlink{toc.subsection.\thesubsection}{#2}}
 \fi}
\makeatother
\let\hypercontentsline=\contentsline
\renewcommand{\contentsline}[4]{\hypertarget{toc.#4}{}\hypercontentsline{#1}{#2}{#3}{#4}}

Answer 1

This both adds the section number to the back link, and removes the section number from the toc line. The latter was definitely harder.
